Evaluation and Analysis of Gas Turbine Internal Flow Restrictors

摘要

A comprehensive review of the literature concerning pressure loss calculations for flow through turns and bends, dividing and combining branches, sudden area changes, and orifices was conducted. An evaluation of the proposed analytical procedures was made on the bases of applicability to gas turbine internal flow systems, accuracy of the flow characteristic predictions, and the complexity of the restriction modeling. A standardized loss analysis procedure for each restriction type was selected from the reliable pressure loss models available in the literature.
